采用弹性力学三维有限元法 ,模拟小浪底水利枢纽孔板塔后增设临时施工竖井对导流洞封堵段的结构影响。通过对比分析 ,对原设计方案配筋作出了评价并对临时竖井的施工提出了工程控制措施。
Three-dimensional finite element method of elastic mechanics is used to simulate the influence of the temporary construction shaft on the sealing section of the diversion tunnel after the orifice plate tower of Xiaolangdi Hydro-junction. Through the comparative analysis, the reinforcement of the original design scheme was evaluated and engineering control measures were put forward for the construction of the temporary shaft.
